# verify-audio-all.sh - Run every port's audio gate and summarise.
#
# Driven by `make verify-audio`. Five gates, two kinds:
#
#   iigs     DOC wavetable + sound IRQ vector          (register tap)
#   x68000   YM2151 noise + PPI port C + ADPCM rate    (register tap)
#   atarist  YM2149 write trace, with the pc           (register tap)
#   amiga    recorded sound, four loudness phases      (Paula has no tap)
#   dos      recorded sound, four loudness phases      (SB has no tap)
#
# SEQUENTIAL, deliberately. The two recording gates drive the emulator on
# wall-clock sleeps and grade fixed time windows of the capture, so a
# second emulator competing for CPU can slide a phase boundary and fail a
# gate that is actually fine. Running five emulators at once also makes
# the timing-sensitive register gates noisier. The whole set is ~2.5
# minutes; parallelism is not worth the flakiness.
#
# Exit codes, distinguishing "it works" from "it did not run":
#   0  every selected gate PASSED
#   1  at least one gate FAILED (a real defect)
#   3  no failures, but at least one gate SKIPPED for a missing
#      prerequisite -- an unbuilt port or absent emulator. Non-zero on
#      purpose: a run that quietly tested nothing must not look green.
#
# Each gate already reports its own evidence line; this only adds the
# roll-up. Gate stdout/stderr is echoed as it happens, so a failure shows
# its diagnosis here and not just a verdict.
#
# Usage:   scripts/verify-audio-all.sh [port ...]
#            with no arguments, all five. Otherwise any of:
#            iigs x68000 atarist amiga dos
# Env:     AUDIO_ALL_LOG   also append the full transcript to this file
# Requires: whatever each selected gate requires; missing ones SKIP.
